Models constructed in eta/DSI are organized into PARTS. These Parts may contain lines, surfaces, and/or elements. Parts may contain only one type of entity or may contain any combination of entity types. Parts may be created from the PART menu.
All data that is created in eta/DSI, such as elements, lines, or surfaces, is created in the CURRENT PART. The current part may be selected or changed from the PART menu. Once selected, all data created is placed in this part.
Parts may be turned on and off for display purposes from the PART menu.
